The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface ... Read More

In this paper, we present the numerical modelling of a free-burning arc and its application to the understanding of optical mirage effect which could occur in a TIG (Tungsten Inert Gas) device used in welding applications. Read More

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis ... Read More

In the paper will be presented the construction of passive magnetic suspension with superconductors. The system of magnetic suspension was designed for GBRIEL project. There is presented numerical test bench of passive magnetic suspension with superconductor. This kind of suspension was ... Read More

Introduction
Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... Read More

This paper presents the study and design of a new generation oven for PET blow-molding machines. The design faced several technical challenges such as: the temperature distribution in the critical areas, the sharp curvature radius, the high PET thermal inertia and the presence of ... Read More

Computational tools based on the finite element method have been used extensively to develop solutions for elastic and elastic-plastic fracture mechanics problems. This work uses a small-scale yielding model to compare results developed from COMSOL Multiphysics® with another finite ... Read More

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... Read More
